CLOTHES WASHING MACHINE I Filed Sept/8, 195s 2 Sheets-Sheet 2 hw'am UR v WITNESS BY W I Mm Patented -Aug. '3, 1937 s PATENT osrlcs Hermann Hill, Rochester, N. Y., asaignor to Easy Washing Machine Gorporation,

S cus N. Y., a corporation oi Delaware Application September 8, was, semi Necessara claims. on; ass-non Thisinvention relates to certain new and useful improvements in-machines for washing clothes and more particularly to a novel dollyor agitator therefor;

An object of my invention is to provide a dolly of simple construction adapted to secure an eisubstantial vacuum cup action on the clothes entirely beneath the surf-ace of the cleansing fluid. I

Other objects and advantages relating to the structure and form and relation oi the parts thereof will more fully appear from the following description, taken in connection with the accompanying drawings, in which:

Figure 1 isa view of my novel dolly in-cross section mounted in a washing vat.

Figure 2 is aperspective view of the dolly showing the cup formation.

Figure-3 is a sectional plan view taken on the line 3+3, Figure 1. Figure 4 is a perspective view form of my novel dolly. 1 Figure 5 isja cross sectional plan view of the dolly shown in Figure a.

My novel agitator comprises a central post or body portion it which ismounted in a vat it substantially centrally thereof. The bottom oi the vat is provided with an opening for the reception of one end of an upstanding sleeve itsecured to the bottom of the vat it, in any suitable watertight manner. The sleeve 13 is provided with a portion it of'reduced internal diameter constituting'an upper bearing for an oscillatory dolly shaftit which extends upwardly from a point .without the vat to a point above the bearing it Any usual and well known means may be pro- ,videdfor oscillating the dolly shaft it through a desirable are, for instance 200 degrees, more or less, and 'I have'here shown a dolly oscillating.

mechanism generally indicated by the numeral 2 which is mounted below the vat i2 and partially enclosed by a depending apron it. A gear l9, mounted on the dolly shaft I6, is oscillated by segmental gear or rack 2| which is reciprocated from any suitable source of power.'

The dolly shaft l6 projects above the bearing of an alternate t and'is formed at its upper end with lengthwise splines or grooves 22 for inner engagement with corresponding splines. or grooves on a bearing member it permanently secured within the upper closed end it oi the central body portion ii The dolly is further supported at bearing member 2t fixed to the internal periphery of the central body portion it which is shouldered at it for reception of the bearing. The bearing member fits snugly on the sleeve it and rotates with respect thereto. In this manner, a driving, connection and support for the dolly is provided by the upper splined bearing member 2t and the dolly is guided by the upper and lower guide bearings it and it respectively.

Extending outwardly from the lower partof the central body portion in a position to contact its lower end by a;

with the clothes to be washed at substantially the bottom of the vat are a-plurality, preferably a pair, of agitating blades ta These blades preferably as shown in Figure 1 extend substantially radially outwardly irom the post or body portion ii and are disposed substantially diametrically k opposite each other and extend vertically about one-half the length of the post i which projects above the normal level pi washing fluid in the tub. The blades merge smoothly into the central'body portionand each of the blades is rounded on one side to form a substantially hemi-spherical surface as at it while the other side is hot-- lowed out as'at it to a substantial depth to proyvide a cup-shaped formation which, when the .dolly isoscillated, will exert a substantial vac! uum cup action on the clothes.

- In Figures 4 and 5, I have shown an alternate form of my novel 'dolly in which the cup-shaped blades are elongated in a direction parallel to the long axis of the central stem whereby when ithe agitator is oscillated in the washing vat, substantially the entire contents of the vat from the botsurface of the cleansing fluid tom thereof to the v is subjected to an efiective vacuum cup action.

In operation, when thepdolly is rotated in one direction, for example, a counter-clockwise direction, as shown in Figure "1. because of the vacuum 'cup,,action, the clothes adjacent the bottom of the vat and in close proximity to the cups are drawn in a counter-clockwise direction with the dolly and at the same time to a certain extent, the vacuum cups tend to draw the cleansing fluid through the clothes. Upon-reversal,- the clothes "are dressed along with the cups andcirculated around the vat in the opposite direction. It will be noted that the cups face in opposite directions,

so that when the dolly is oscillating, because less resistancelsofleredto thepassageoi'the dolly through the cleansing fluid by the head-spherical direction. Although as has been said, this resultsuriace'of the blades than by the cups, the resultant action although substantially equal in bothdirectionsissuchasto cause aslighttendency io'r the clothes and washing fluid to circulate predominately around the vat in one ant movement oi the clothes in one direction .is

slight, the clothes to casual observation appeara ing to be moved with equal force in h'oth'dire'c tions, it is suflicient when combined with the-na'tural agitation set by the blades to cause new clothes surfaces to be constantly presented to the washing action of the vacuum cups.

The action of the dolly shown'in Figures 4 and 5 is substantially thevsame as that described with respect to Figure 1 with the exception that substantially the entire contents of the vat from the'bottom of the vat to the surface of the liquid is subjected to the vacuum cup action above described.

It is apparent that I have provided a novel oscillatable dolly ;which is adapted 'to secure an efl'ective vacuum cup action on the clothes'and that various modifications may be made in the form and relation of parts thereof. I, therefore, do not desire to restrict myself to the details of the construction and form illustrated except where the same are specifically included in the claims hereto appended, as various changes and modifications may be made without departing irom the scope ofrmy invention.

I claim:

' 1.' In a machine for washing clothes, a'v'at, an ag itator mounted therein, said agitator comprising an upstanding central portion and a plurality of blades extending. from the central portion.

aosaoos of? ms presenting ahemispherical unobstructed-surface on one side to the washing fluid and'being cup-shapedon the other side. and

means for oscillating said agitator, the cupshaped'suriaoesofsaid bladesbeingamngedto produce circulationoi'clothes. and washing fluid inm'edirectionaroundthevat.

, .2. A e for washing clothes comprising a vat for containing clothes to be washed and washing fluid, an osciliatable agitatormounted in said m, means extending through the bottom of the vat for oscillating said agitator, said agitator comprising a central portion and a pair of clothes washing elements radiating outwardly from said central portion, each of said clothes washing elements presenting a hemispherical surface to the washing'fluid on one-side and a vacuum cup surface to. the washing fluid on the other side, said vacuum cup surfaces-facing in opposite directions.

. 3. In a-machine forwashing clothes, avat for containing the clothes and washing fluid, an oscillatable' agitator mounted in said vat, means extending-through the hotto'm oi the vat for oscillati'ngsaid agitator, said agitator comprising a central post and a plurality of blades extending from said central post, said blades each having a hemispherical unobstructed surface presented to the clothes and washing fluid in one direction of rotation of the agitator and having a cup-shaped surface presented to the clothes and washing fluid in the other direction of rotation of the agitator whereby the opposite faces 01' the blades exert-an unequal thrust to .cause the clothes and washing fluid to circulate in pne direction around the vat.
